Rotating regulating device

Abstract

A rotating regulating device for the rotation and/or linear displacement of an actuating element of a valve, throttle, blowout preventer or similar, in particular in the field of gas or oil supply, exhibits a spindle drive and a drive train rotationally driving the spindle drive, the said drive train exhibiting at least one reduction gear unit and a drive device connected to it for movement. In order that the regulation of the actuating element is possible in an extremely accurate, finely controlled and reproducible manner even with different drive devices and with simple and compact construction, the rotating spindle or nut of the spindle drive exhibits at least one engaging element, essentially protruding radially outwards, which engages guide slots, whereby a first guide slot is fixed relative to a device housing and a second guide slot can be rotated relative to the device housing and/or is supported for displacement in the longitudinal direction of the rotating spindle, whereby the guide slots exhibit at least different slopes in the longitudinal direction of the rotating spindle and the movable guide slot is connected for movement to the actuating element.
